}

le resultat: c'est que la liste des id de l'employee est chargé dans le select mais en selectionnant l'id ,les autres attribut ne sont pas affichés dans le formulaire.voici le message figuré dans la console:
juil. 2008 17:24:35 javabeat.bean.EmployeeBean onSelectId
INFO: Chargement du l'employee :
Hibernate: select employee0_.id as id0_0_, employee0_.Name as Name0_0_, employee0_.Age as Age0_0_, employee0_.Salary as Salary0_0_ from Employee employee0_ where employee0_.id=?
4 juil. 2008 17:24:35 javabeat.bean.EmployeeBean onSelectId
